Hi, my notebook is an HP Pavilion DV7 with a Radeon Hybrid Card. I had Ubuntu 10.04 32bits and the patch Kamal made worked for me using the following kernel Params: *radeon.modeset=0 (disables radeon discrete card) *acpi_backlight=vendor (kamal patch)
Now I updated to Ubuntu 11.10 64bits and the patch is supposed to be already in the kernel. The problem is that if I use the second param, I get a black screen almost all of the time, and some few times the systems boots correctly with the brightness control working correctly. Is there any way to solve this? I would appreciate it very much! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/568611 Title: Screen brightness control fails on Dell Studio 1558 To manage notifications about this bug go to: https://bugs.launchpad.net/null/+bug/568611/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
